Before moving on ask yourself if you've met the Learning Targets for this week:

Identify sources of genetic variation Describe how natural selection acts on the distribution of traits in a population Explain how gene flow, genetic drift and sexual selection can lead to the evolution of populations Identify the conditions that define Hardy-Weinberg equilibrium Describe how populations can become isolated Explain how isolation of populations can lead to speciation

If not take the time to review the ones you are uncertain of, and let your teacher know if you need more help on any of these.
